Description

We use azcopy to copy segments from one azure blob container to another for testing. There is a bug in the current version of azcopy (10.3.3), which makes all metadata keys start with a capital letter - "type" becomes "Type". As a consequence, the current implementation can not find the segments in the azure blob storage. 
 
The azcopy issue was already reported [1] in 2018. I have little hope that azcopy will be fixed soon.
 
Therefore I suggest a patch to oak-segment-azure, that would be backward compatible and ignore the case of the keys when reading metadata. We should be strict in what we write and tolerant in what we read.
